I'm not sure why kenwood felt the need to produce this receiver. Maybe just because they could. Separates are usually preferable for several reasons, but duel power supplies deliver a sound that is unrivaled, separates or not. The kr-9050 doesn't even weigh as much as you'd think. And it looks great. I love vintage kenwoods. And i love my kr-9050.

Yesterday was one lucky day for me. I picked up this KR-9050 for $50 from a guy who had stored in a storage unit. Kind of dirty but from 3 feet the face looks almost mint. Top is fair. Wood sides are rough .Will replace sides. All knobs present & glass was clean.Took it home & deoxit the hell out of all switches & it sounds amazing. It's a keeper for sure.
The FM sounds better than I ever heard.

After 34 years this receiver still kicks ass! Performs like new, cranking nearly full power into Genesis Model II speakers with upgraded 250W woofers. It shakes the house!



re: KR-9050

As one person stated, after 34 years it might "kick ass" but undoubtably will require going over nevertheless.
Because after 30+ years there are some parts that naturally have aged and gone out of spec - causing improper operating conditions not audible to the ear - yet will potentially cause damage.

Front Panel Lamps - what type and where do I get fresh front panel lamps for my KR 9050?

re: KR-9050 Front Panel Lamps

Try looking at JKL company as they have a lot of lamps there. I bet the DA513 that I use in meters would work just fine. Tey only take 55mA so less demand on the supply.

re: KR-9050

I own this receiver. After 34 years it still kicks ass. The specs are better than half the receivers on the market today! Some of the nobs are a little finicky and occasionally there is some static while flicking switches and turning nob,s but over all it is awesome! I have it paired with a set of Genesis Physics Model II speakers that I replaced the woofers in. They are now 250W each. It shakes the house! I love it!

re: KR-9050

I am a new member from Australia and it is hoped, I am welcome to post in this interesting forum.

I am also new in the field of hi-fi and I intend to get a Kenwood model ref KR-9050. After reading some reviews and reports, I reckon this is a powerful and reliable machine. However I would like to know, whether or not it has multi-tapped transformers, so that I can switch machine for Australian use: current is 220-240V instead of the American's 110-120V.

re: KR-9050

There are three versions.

The US and Canada tend to get the pure 120 only wired transformer version. (single pair of input wires, 120 only, nothing else even possible)

Then there is the 110-220 volt switchable version.

And finally, the 120-240 volt switchable version.

All three will work in Canada and the USA, as the step down is to a 53VAC rail, from 120 or 110V, so the differences are about 5% on the final DC rail voltages.

If you are careful, you may find one of the switchable voltage units. But your best bet is to look for the euro/Asian/mideast/etc market version.
